Awesome idea for frame!!!
Hey my fellow jeepers a great idea hit me today while working on my jeeps frame!!! If you dont know im rebuilding my jeep from the body tub to the frame not one part of my jeep has not been touched. :thumb:
but the main thing im focusing on is the frame and my idea of how to get inside the frame rails to prevent it from rusting out like my old frame did (AKA) why im redoing my jeep and its been a pain in the butt for sure :banghead: in other news i have herd to use expansion foam, just spray paint down the rails, use eastwood frame coating, just leave it, weld the factory holes... so on and so forth well im on a tight budget and i want this thing to last i love my jeep so much i never want to see this happen again so here is the idea :popcorn:
While working on my jeep i thought well what if i seal the holes with duct tape and then fill it up with... some kind of a tar :eek: (wow did he say tar) yes i did! now before you all go saying well why not use rhino lining instead of a asphalt tar? well that would work to the theory is if you lift your frame up on the rear end and block all the holes in the frame with tape of some kind and then get a 5 gallon pale of WHAT EVER KIND OF TAR/PAINT!!! and dump it down the frame to were it fills both rails. now yes you would do this 2 times for each rail... then when she soaks in and you think its coated in there nice pull the tape or sealer off and let it drain out. Now i know your thinking this will make a huge mess yes so do it some were that you dont mind tar/paint getting every were. But the theory is with tar in the rails water, dirt, mud what ever will not rot the inside of the frame rails hell the outside paint should go before the tar does right???:confused:
Now im planing on doing this what i will use idk this thread is not debating product would work better its about the idea. now i know there is someone out there thats going to say oh blah blah blah thats dumb... well everyone has their own opinion what ever. But please tell me what you think of this idea the main thing is that it will coat the inside sooo dang good because it will get top bottom both sides of the rails and tar is amazing verses water dirt and all that stuff that will kill your frame.

Well thanks for looking at the thread im curious of all your opinions to this idea. I also dont see anything on the internet with this idea so hey maybe it will work who knows??? so leave me a comment on this and let me know how you feel about this THANKS ALL and keep on JEEPING!!! :punk:

I'd be interested to see how well that would work. I think you would have to lift the front to coat the back also. It would be better than nothing, but I'm not sold. I'll be Eastwooding mine soon, and I keep thinking about foaming it afterward. My concern is that with my luck, it will crack the frame when it expands.

What kind of chemical reaction occurs when tar meets metal? Rust?

MrMuddy 07-13-2012 11:59 PM

Why not use por 15 rust perventor.

I'd be careful about using expanding foam. The stuff isn't closed cell and does absorb water over time. It's also susceptible to breaking up due to freezing and thawing when damp. One product I've used on steel that provides very good rust protection is cold galvanizing. Several companies make cold galvanizing paint in spray cans or bulk cans. The stuff works excellently. On spray can coat kept rust off my Ford step bumper for years. On other thing to consider is to be careful not to plug up drain holes those are prevent water from pooling inside areas where you don't want water standing.

(Harryjeepguy) yes you would have to lift it up and dump it down the front of the frame useing a funnel or something. also i used the Eastwood internal frame paint in the rails did not cover as good as i wanted maybe if i bought alot of cans and did it would work better but that stuff gets pricy for me at least. But honestly im at the same point as you did not know if i should use the expansion foam or not but i might do this and do a video of it good luck with what you pick to do man i just hope it works for you BEST OF LUCK =)

there would be no reaction at all tar is a sealer look at your driveway if its blacktop better yet go look at a highway thats your basic tar and it stick to everything

thats a good idea to i do not disagree with using it just por 15 is also very expensive a gallon of por runs about $150 when a 5 gallon pale of tar is like $25 in home depot lows and most hardware stores. but if you have the money go por thats also a great idea :thumb:

You're overthinking it. Keep the frame cleaned out and touched up and it should last longer than you'll ever need it to....all you need is a low pressure hose. I work under my rig a lot and have done a lot of frame modifications....I would never want to mess with tar, bed liner, oil, or any of the other ideas thrown around. If you NEVER work on your rig and NEVER wash it, do whatever you want.

rrich 07-14-2012 06:32 PM

I'd think any kind of crud you'd put in it would only hold moisture in causing major rust.

Bedliner stuff is used out in the open where it can dry out.

Foam isn't designed to be trapped in steel and it's too porous.

Maybe heat the frame to make sure it's totally dry, then pour epoxy though it. Keep it hot until the epoxy sets up. Probably more trouble than it's worth but you'll feel good about it.

Just keep it clean - wash out the mud and salt frequently, then let it dry. Maybe even put a few more drain/vent holes on the bottom so it can dry out better.

Or move to a less wet state.

Same problem here in the desert - dust gets trapped, then holds in the moisture, then rusts after 3 or 4 hundred years. That's probably why you don't see many 400 year old frames.

Best idea so far.

"""""Cosmoliene Lives forever. """""

Good idea, but how do you apply it?

Gunner 07-15-2012 02:56 AM

Heat it up and pour it in.

Tweeter 07-15-2012 03:54 AM

I don't know about how it would handle in NY....but for a good part of the year in the southwest you can go out on any day and play with the tar in the road...the heat re-softens it....not sure how that would fair in the body of a vehicle

Derp 07-15-2012 05:57 AM

Drill a hole in front and behind the bend in the frame in the rear. That's the main area where water sits, and flush the frame out everytime you get in water or mud.
